Sure. But you can't buy them. You can only get them if you sign up for their monthly service, "Nintendo Switch Online." And you can't have all of them. You can only get the N64 games if you sign up for the separately monthly. "Expansion Pack" service. And you can't play them on multiple profiles. Your son can only play Mario 64 on his profile if you sign up for the "Nintendo Switch Online + Expansion Pack + Family Pack" subscription, which is about $80 per year. It's so expensive because they bundled it with a bunch of other stuff (hooray now I can also play Switch games online and I have access to the latest patch for Animal Crossing and some extra tracks for Mario Kart).
But I just wanted to let my son Mario 64, and $80 per year is too much for that.
